You cannot catch Raikou in Pokemon Black. You have to transfer it from Diamond, Pearl, Platinum, Heartgold, or Soulsilver.
You will have to either trade for Raikou or transfer from Diamond, Pearl, Platinum, HeartGold, or SoulSilver.

I have a Shiny Event Raikou, but it depends on what you're going to trade. If you want to trade then put a message on my message board. - PokemonShaymin102
You have to get one on a Diamond, Pearl, Platinum, Heartgold, or Soulsilver first. Then you have to go to the poke transfer lab in your Black or White version to transfer your Raikou over. BTW you have to bring five other Pokemon over too.
